Matthew 10:16 Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.
Jesus did not send the disciples blindly out into the world but gives them a stark warning of the danger before them as they go forward.
Our walk in this world is not going to be straight-forward or easy going when we show others we are willing to follow Christ; we will face many dangers and trials just as the disciples did.
We need to be able to face up to the world by being bold enough and intelligent enough to stand up to the people; but also without wrath so as not to bring on discord.
Asking God for wisdom enough to avoid the pitfalls is wisdom.
